  987. 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket

  988.   Move AVPacket declaration from libavformat/avformat.h to

  989.   libavcodec/avcodec.h.

  990. 

  991. 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats

  992.   Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,

  993.   PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.

  994.   Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and

  995.   PIX_FMT_BGR32_1 are now macros.

  996.   avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

  997.   Re-sort the enum PixelFormat list accordingly.

  998.   This change breaks API/ABI backward compatibility.

  999. 

  1000. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  1001.   Add the enum PixelFormat values:

  1002.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  1003.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  1004. 

  1005. 2009-03-21 - r18116 - lavu 50.0.0  - av_random*

  1006.   The Mersenne Twister PRNG implemented through the av_random* functions

  1007.   was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  1008.   instead.

  1009. 

  1010. 2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer

  1011.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  1012.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  1013.   and av_fifo_realloc2.

  1014.   In addition, the order of the function arguments of av_fifo_generic_read

  1015.   was changed to match av_fifo_generic_write.

  1016.   The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by

  1017.   applications, they may not use sizeof() or directly access members.

  1018. 

  1019. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API

  1020.   Introduce a new metadata API (see av_metadata_get() and friends).

  1021.   The old API is now deprecated and should not be used anymore. This especially

  1022.   includes the following structure fields:

  1023.     - AVFormatContext.title

  1024.     - AVFormatContext.author

  1025.     - AVFormatContext.copyright

  1026.     - AVFormatContext.comment

  1027.     - AVFormatContext.album

  1028.     - AVFormatContext.year

  1029.     - AVFormatContext.track

  1030.     - AVFormatContext.genre

  1031.     - AVStream.language

  1032.     - AVStream.filename

  1033.     - AVProgram.provider_name

  1034.     - AVProgram.name

  1035.     - AVChapter.title
